Becky Smith, 20, whipped her phone out as Mr Cameron stopped at her table to wish her friend a happy birthday. The PM was dining out at the fast-food outlet in Bristol, tucking into half a chicken, chips and coleslaw with a glass of red wine.

The arresting sight came as marked patrol cars were spotted lined up outside the Krispy Kreme joint in Bristol. And onlooker Paul Amery said a FIFTH was out of view of his camera buying more of the sugary treats on Monday morning.
